Forceful comments underlined with mockery by U.S. President

President Barack Obama made some of his most forceful comments to date about global warming in his 2015 State of the Union address.

The U.S. president mocked the Republican reluctance to acknowledge man-made climate change and warning Congress against attacking his efforts to curtail greenhouse gas emissions.

Obama spoke about climate change late in the 63-minute long speech. But his rhetoric was blunt. "No challenge — no challenge — poses a greater threat to future generations than climate change," he said. "That's why, over the past six years, we've done more than ever before to combat climate change, from the way we produce energy, to the way we use it...And that's why I will not let this Congress endanger the health of our children by turning back the clock on our efforts."
